The state's annual tax revenue is nearly $9.9 billion, placing it close to the median range nationally. Both residents and nonresidents who do not live in the state but earn income from the state must file Kansas tax returns. Anyone who lives in the state for less than 12 months may file as a resident or a nonresident.
